A lioness and cub have similarly traumatic experiences, but they forge a beautiful , unshakable bond of friendship the moment they meet.

Because the cubs can have different fathers, there is an incentive for male lions to have the biggest offspring. He would want his cubs to do better than their littermates!

On the other hand, the lioness is mother to all the cubs in the litter. She wants all her babies to have an equal chance at surviving! Ideally, she wants all the offspring to be medium size so that she will have a successful pregnancy and be able to care for the cubs once they are born. Unlike lions, they are mostly solitary.

Tigresses only mate with one male tiger at a time. All her cubs will have the same father. This means the reproductive goals of male and female tigers are the same. A pride of lions Image from Pixabay Imprinting adds instructions to DNA sequences But how do reproductive goals result in genetic differences?

Mammals have evolved a way to pass on maternal or paternal goals to their offspring. They do this by imprinting. DNA is like an instruction manual. But instead of having the instructions for building a chair or a table, it has the instructions to build living things, like lions and tigers.

While sperm and eggs are in the adults, prior to fertilization, their DNA can be modified. These modifications do not change the DNA sequence itself.

For example, the instructions might read: Sand down until completely smooth and then paint pink. You could underline certain parts to give them emphasis, such as: Or you could cross out an instruction you decided you did not want to follow, such as: You can make these modifications without changing any of the words in the manual.

The process in which these types of modifications are made to the DNA in eggs or sperm is called imprinting. What are other examples of imprinting? One of the most well-studied cases of imprinting is in mice. Just like lions, female mice can have litters with pups from multiple fathers. Therefore, male mice want their offspring to be big, so that their pups survive best from the litter. Female mice want all their offspring to be of moderate size.

The version that is inherited from the father is underlined, telling the embryo to grow a lot. The version inherited from the mother is crossed out, telling the embryo not to grow too much.

Therefore, only the Igf2 gene inherited from the father is active. Imprinting does not change the DNA letters themselves. Asiatic lion prides differ from African prides in group composition. Male Asiatic lions are solitary or associate with up to three males, forming a loose pride. Pairs of males rest and feed together, and display marking behaviour at the same sites.

Females associate with up to 12 other females, forming a stronger pride together with their cubs. They share large carcasses with each other but seldom share food with males.

Female and male lions associate only when mating. Males in coalitions of three or four individuals exhibit a pronounced hierarchy, in which one male dominates the others.

Dominant males mate more frequently than their coalition partners; during a study carried out between December and Decemberthree females were observed switching mating partners in favour of the dominant male.

Lions kill other predators such as leopardcheetah and spotted hyena but seldom consume them. In Serengeti National Park, wildebeest, zebra and Thompson's gazelle form the majority of lion prey. Up to eight species comprise three quarters of a lion's diet. The prey-to-predator weight ratio of 10— Cooperatively hunting lions are usually successful. Males attached to prides do not usually participate in group hunting.

They take advantage of factors that reduce visibility; many kills take place near some form of cover or at night. To protect their cattle from such attacks with that knowledge in mind, farmers have found it effective to paint eyes on the hindquarters of each cow, which is usually enough to make hunting lions think they have been seen and select easier prey. They also kill prey by enclosing its mouth and nostrils in their jaws, which also results in asphyxia. Cubs suffer most when food is scarce but otherwise all pride members eat their fill, including old and crippled lions, which can live on leftovers.

On hot days, the pride retreats to shade with one or two males standing guard. Scavenging lions keep a constant lookout for circling vultures, which indicate the death or distress of an animal. Lions seize the kills of spotted hyenas; in the Ngorongoro crater it is common for lions to subsist largely on kills stolen from hyenas, causing the hyenas to increase their kill rate.

The two species attack one another even when there is no food involved for no apparent reason. Spotted hyenas have adapted by frequently mobbing lions that enter their territories.
